Sender unit question

[Grant Bowker]

My understanding is that the original senders should work. Ohms are Ohms. The "special" part about Chevs is that they used a different resistance range than either their contemporary Ford or more modern Chevs. I think the resistance range used on Chevs with the commercial gauge cluster and the round instruments were the same 0-30 Ohms. The important part is that the gauge and sender need to match (hence the voltage reducer at the gauge to make it match the original sender).
